IMPROVEMENT IN BREECH-LOADING FIRE-ARMS.

Specification forming part of Letters Patent No. 160,9l5, dated March16, 1875; application filed February 6, 1875.

To all whom it may concern:

Be it known that I, CHARLES A. KING, of Meriden,in the county of NewHaven and State of Connecticut, have invented new Breech- LoadingFire-Arms and I do hereby declare the following, when taken inconnection with the accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in-

Figure 1, side view Fig. 2, longitudinal section; Fig. 3, transversesection, showing the joint; Fig. 4, perspective view of the stop.

This invention relates to an improvement in that class of breech-loadingfire-arms in which the barrel is hinged to the forward end of the frame,and arranged to tilt up at the breech.

The object of the invention is to take the strain from the pintle of thejoint; and it consists, first, in the employment of a collar on thepintle, prevented from turning by connection with the frame, independentof the pintle, and with a projection or shoulder from said collar toform the stop; second, in the method of finishing the frame around theend of the pintle, as more fully hereinafter described.

A is the frame; B, the barrel or barrels, (here represented as twobarrels,) hinged to the frame by a pivot, C, so as to tilt up at thebreech, and secured in the closed position by any known or desirabledevice, that shown being the Miller patent, or better known as theParker gun, and no part of this invention. In the forward end of theframe, between the ears D D, the collar E is placed, it being bored out,so that the pintle C will pass through the ears D and the pintle to holdit between the cars. This collar is cylindrical in form on its backside, so that the lug F on the barrels, correspondingly shaped,will hookonto the back of the collar, as seen in Fig. 2, and substantially as itdoes in the usual construction. On the upper side of the collar is aprojection, a, against which a shoulder, d, on the barrels will strikewhen the barrels are tilted, as denoted in broken lines, Fig.2, thusforming a stop to limit the extent of the open ing. This projection aalso serves to operate the extractor-rod L.

This is the usual construction.- The collar is prevented from turning byits connection with the pintle, and the pintle prevented from turning byits connection with the frame. In such constructions the strain for thesupport of the open barrels comes entirely upon the pintle, except sofar as it is relieved by a shoulder on the tang P striking the end ofthe recess in the frame. The tang closes upon the front surface of thecollar to complete the hinge, in the usual manner. To take this strainfrom thepintle, a connection of some character is made between thecollar and the frame to prevent the collar from turning. This is bestdone by the projection 11 on the side of the collar, and a correspondingrecess in the side of the slot in the frame, as seen in Figs. 3 and 4,and as an additional preventive a projection, e, on the lower side ofthe collar bears against the end f of recess in the frame. By thisconstruction the strain is almost entirely taken from the pintle, sothat it may be leftin perfectly cylindrical shape. The shoulder 11, onthe tang P strikes the front of the projection e at the same time theshoulder d on the barrel strikes the back side of the projection a.

p In transverse section the frame at the pintle C is elliptical, and theends of the pintle must be correspondingly finished; hence, if thepintle be not set in exactly the position it is then finished, its endswill not come flush with the surface of the frame, necessitating aspline on the pintle, or other device, to indicate the exact position itmust occupy, or there is considerable difficulty in adjusting thepintle. To obviate this difficulty a spherical recess, R, is formed oneach side of the frame at the pintle perforations, the axis of eachrecess in line with the axis of the pintle, as seen in Figs. 1 and 3,thus bringing the ends of the perforations into an annular plane, sothat the ends of the pintle will come flush with such annular surface,whatever position (circumferentially) the pintle may be set in place.

Having thus fully described my invention, what I claim as new anduseful, and desire to receive by Letters Patent, is-

1. In a fire-arm the barrel of which tilts up at the breech, the collarE, constructed with a connection to the frame other than the pintle,substantially as described.

2. In a fire-arm the barrel of which tilts up at the breech, therecesses R in the frame around the pintle, substantially as and for thepurpose described.
